Measuring 4 inches in diameter and 1\/2 inch thick with a 1\/2 inch arbor hole, this coarse-grade wheel runs at a maximum of 5,250 RPM. The rubber bond matrix cushions cutting action, reducing chatter and allowing consistent surface contact across uneven workpieces. Green in color, the wheel is suited for tasks requiring controlled abrasion without aggressive stock removal. It is used by machinists, metalworkers, and maintenance technicians who need a reliable tool for surface prep and finishing operations.\u003c\/p\u003e\n\u003cp\u003eThis wheel is built for bench grinder and surface grinder applications in machine shops, maintenance facilities, and light industrial environments. Rated applications include corrosion removal, deburring, excess solder removal, heat mark cleanup, polishing operations, rust removal, scratch blending, surface smoothing, and tarnish removal. It fits standard 1\/2 inch arbor spindles common to bench grinders and pedestal units in both shop and field service settings. The coarse grade makes it effective for initial surface conditioning before finer finishing steps.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSilicon carbide abrasive grain for effective cutting on ferrous and non-ferrous metals\u003c\/li\u003e\n  \u003cli\u003eRubber bond construction cushions cutting action and reduces chatter\u003c\/li\u003e\n  \u003cli\u003eCoarse grade for aggressive surface conditioning, deburring, and rust or corrosion removal\u003c\/li\u003e\n  \u003cli\u003eRated to 5,250 RPM maximum for safe use on standard bench and pedestal grinders\u003c\/li\u003e\n  \u003cli\u003eNo recess design simplifies mounting on standard flanged arbors\u003c\/li\u003e\n  \u003cli\u003eGreen wheel color provides visual identification of silicon carbide bond type at a glance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with bench grinders and surface grinders fitted with a 1\/2 inch arbor.

Before mounting, power down and lock out the grinder per OSHA lockout\/tagout procedures. Inspect the wheel for cracks or chips before mounting, and never exceed the rated 5,250 RPM. Ensure flanges, blotters, and arbor hardware are in serviceable condition and that the arbor size matches the 1\/2 inch hole before securing.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eArbor Hole Size\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Silicon Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Rubber\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 5,250\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Green\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecess Type\u003c\/strong\u003e: No Recess\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: CRATEX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 408 C\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CRATEX","offers":[{"title":"Default Title","offer_id":67906414018866,"sku":"408 C","price":70.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dda39f4f4a7ea75d53fac93ac55d500e.jpg?v=1791167930","url":"https:\/\/voomisupply.com\/products\/cratex-408-c-surface-grinding-wheel-4in-silicon-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
